Application filed February 2, 1910.

To all whom it may concern:

Be it known that I, ALPHoNsn BRIFFOD,

a citizen of the United States of America,

residing at New Orleans, in the parish of Orleans and State ofLouisiana, have invented certain new and useful Improvements inReinforced-Concrete Jackets for Piling, of which the following is aspecification, reference being had therein to the accompanying drawing.

My invention relates to an improvement in a reinforced concrete jacketfor piling, and its novelty will be fully understood from the followingdescription and claim when taken in connection with the annexed drawingsand the objects of my invention are to provide a means for preservingpiles for an indefinite period and prevent them from being destroyed byworms or insects that exist in alluvial soil or water. I attain theseobjects by the mechanism illustrated in the accompanying drawings, inwhich;

Figure 1 is an end view, showing pile in jacket. Fig. 2 is a verticalsection showing pile when driven into position, reinforced and in aconcrete jacket. Fig. 3 is a sectional View.

Similar numerals refer to similar part-s throughout the several views.

In the drawings, 1 designates a pile which may be of any form.

2- is a concrete mush or mass.

3 is a reinforced shell.

l is a wire netting placed in position in the manner shown in Figs. 2and 3 and forms an interior part of reinforced cover.

5 are steel bars placed in position as shown in Figs. 1, 2 and 3 andgive strength to the interior portion of jacket, and when these barsproject in the manner shown in Fig. 3 enable the placing of structure orextension upon same.

Specification of Letters Patent.

Patented June 21, 1910.

Serial No. 541,644.

6 is a ring cast in upper part of rein forced shell.

7 shows top of bed soil under water and into which pile is driven.

8 shows water line.

In practice the pile is driven in the usual manner, the outer shell andnetting being placed in position and the water is pumped out of theshell. The concrete is then by any suitable means placed around the pileand between the netting and the outer shell and the steel bars placed inposition and when these formalities have been complied with, the pile iswithin a reinforced jacket which is impervious to water or the ravagesof worms or insects which infest the water fronts of docks on tidewater.

The advantages of my invention are its economical construction, anddurability.

Having described my invention and the manner in which the same is or maybe can ried into operation would say in conclusion that I do not limitmyself to the precise details shown in illustration, as the same may bevaried to some extent, but

What I claim and desire to secure by Letters Patent is- The combinationwith a pile of a protecting covering comprising an outer reinforcedshell and inner concrete filling between the pile and said shell,vertical reinforcing bars in the concrete filling and a ring in theupper part of the shell.

In testimony whereof I aflix my signature in presence of two witnesses.

ALPHONSE BRIFFOD.
